Congruent-melting composition of langasite (La_3Ga_5SiO_<14>) was studied by a combination of melting-point measurement, crystal growth and compositional characterizations. The melting points of sintered samples with various compositions within the solid solution range determined by X-ray diffraction (XRD) around the stoichiometric composition were measured by differential thermal analysis (DTA). Upon the growth of single crystals from the compositions with high melting points, the compositions of various parts of the as-grown crystals and the residual melt were investigated by X-ray Fluorescence Spectrum (XFS). The congruent-melting composition was determined to be the initial composition from which a minimum deviation of composition of both the crystal and the residual melt was obtained.
